Chord Electronics Étude 150W Stereo Power Amplifier

Welcome to the pinnacle of sound performance with the introduction of the Chord Electronics Choral Étude, a revolutionary 150W Class AB stereo power amplifier. Representing a breakthrough in amplifier design, the Étude incorporates cutting-edge aerospace-inspired technologies to deliver unparalleled audio quality.

Unrivaled Dynamics and Precision

Designed to complement and maximize the potential of the award-winning DAVE DAC, the Étude features a groundbreaking new amplifier topology that ensures lightning-fast power delivery. This innovative design offers exceptional dynamics, lifelike transient response, and precise control over loudspeaker drive units, resulting in a truly immersive listening experience.

Advanced Amplification Technology

The Étude employs a multi-feedback and dual feed-forward error-correction amplifier technology, intelligently optimizing the linearity of its high-power proprietary MOSFETs. With three individual high-frequency switch-mode power supply units and advanced internal shielding, the Étude delivers crystal-clear sound reproduction with remarkable speed and accuracy.

Enhanced Power and Flexibility

Despite its conservative 150W rating into 4Ω, the Étude can be configured for bridged mono mode, doubling its power output to an impressive 300W into 4Ω. This versatility ensures compatibility with a wide range of speaker systems, allowing you to tailor your audio setup to suit your preferences.

  • Class AB Sliding Bias: Utilises Class AB sliding bias for optimal performance and efficiency across various load conditions.
  • HF Switch Mode Power Supply: Incorporates a high-frequency switch mode power supply for reliable and efficient power delivery.
  • Chord MOSFET Construction: Features Chord MOSFET construction for enhanced audio quality and reliability.
  • Fully Balanced Circuitry: Utilises fully balanced circuitry to minimise noise and distortion for pristine audio reproduction.
  • Fan Cooled: Equipped with a fan cooling system to maintain optimal operating temperatures during prolonged use.
  • Stereo Balanced XLR Inputs: Offers stereo balanced XLR inputs for high-quality audio connectivity.
  • Stereo Unbalanced RCA Inputs: Includes stereo unbalanced RCA inputs for versatile connection options.
  • Solid Aluminium Chassis: Constructed with a solid aluminium chassis for durability and effective heat dissipation.
  • Bridgeable to 300W - 4Ω: Bridgeable configuration allows for increased power output, up to 300W at 4Ω impedance, for flexible setup configurations.
